Sia to release new music

Sia will drop seven new tracks later this year as part of a Deluxe Edition of her album 'This Is Acting'

Sia is planning to release seven new tracks later this year.

The 40-year-old singer has announced that she's making a Deluxe Edition of her 'This Is Acting' album and is keen to add her recent single 'The Greatest', which features Kendrick Lamar, and three previously unheard songs called 'Confetti', 'Jesus Wept' and 'Midnight Decisions' to the listing.

Sia - who is known for disguising her face behind her signature blonde wig - dropped 'This Is Acting' in January and it has so far climbed to number three in the UK charts.

The 'Chandelier' hitmaker revealed ahead of its release earlier this year that the album features songs that she'd written for other artists but they'd been rejected.

She said at the time: "I'm calling it 'This Is Acting' because they are songs I was writing for other people.

"I didn't go in thinking 'this is something I would say'. It's more like play-acting. It's fun."

Meanwhile, Sia recently admitted doesn't enjoy being in the spotlight because it has a negative impact on her self-esteem.

She said: "It literally f**ks with my sanity. I stop feeling authentic because I'm trying to find ways to say the same thing differently. And after a while, you can't. It becomes bad for my self-esteem.

"People say, 'Enough of this s**t where she doesn't show her face'...I'm trying to do this differently, for serenity. And it's a fun game for me as well. I have nothing to lose.

"But of course I want to be loved. So when people say, 'Show your face, you're not ugly.' I want to say, 'I know. I'm not doing it because I think I'm ugly; I'm trying to have some control over my image. And I'm allowed to maintain some modicum of privacy. But also I would like not to be picked apart or for people to observe when I put on ten pounds or take off ten pounds or I have a hair extension out of place or my fake tan is botched. Most people don't have to be under that pressure, and I'd like to be one of them."
